The first Tudor chronograph, named the Oysterdate, was launched in 1970. Having immediately become associated with mechanical sports watches, the Oysterdate was generously proportioned, and had an unusual dial design.
Three variations of these watches were created: Reference 7031, Reference 7032, and Reference 7033, each of which was distinguished by its bezel type. Reference 7031 featured a bezel topped by a Plexiglas disc whereas Reference 7032 had a satin-brushed steel bezel. Being the classic design of the Oysterdate, these watches were perfect for collectors looking for a timeless piece.
The watches' pentagonal hour marker had earned this model the name "Homeplate", which appealed to baseball fans the world over.
Reference 7033, the third variation for this model, had never gone beyond its prototype stage.
